Q:

How do I sterilize soil?

A:

The easiest way to sterilize soil is by baking it in a 180-degree oven for 30 minutes. All you need to sterilize soil in the oven is a large baking dish, aluminum foil and a meat thermometer.

  1. Prep the Soil

    According to Colorado State University, soil must be moist before baking. Water dry soil with clean water, and add any desired additions to the soil, such as manure or peat moss. Mix the additions into the soil thoroughly.

  2. Add the Soil to a Baking Dish

    Add the desired amount of soil to a baking dish. Spread the soil out evenly in the baking dish. Two to 4 inches of soil is the maximum amount of soil that should be in each baking dish. Place a sheet of aluminum foil over the baking dish, and seal it tightly.

  3. Bake the Soil

    Place the baking dish of soil in a pre-heated, 180-degree oven. Bake the soil for 30 minutes. Insert a meat thermometer in the middle of the dish so you can read the temperature of the soil.

  4. Cool the Soil

    Turn the oven off after 30 minutes. Leave the soil in the oven until it is completely cool. Remove the baking dish once the soil is completely cooled. Leave the aluminum foil on the baking dish until you are ready to use the soil.
